The facial features are too washed out. If you increase the contrast a bit, they will better match the painting.

I think it looks fine, a high resolution would be nice. Pretty subject matter, nice job on the shadow work. Edit: good Hi Res.

Better, but now her face is a bit too pinkish in tone, giving her face a somewhat sunburned look (notice the pale tone on her hands and below her neck). You can try adjusting the Brightness and Contrast, or perhaps Image>Adjustments>Selective Color and then lightening the red tones (possibly the magenta) so that the values match.

looks great author

Hard to judge with no hi-res. Please realize a hi-res image is pretty much mandatory if you want to get a decent vote.

Nice positioning and good model choice...IMHO shadowing on her face should be bit better...u have to simulate brush moves so regular soft brush is not good for that...maybe u should use chalk brush for starters and try to create that effect in few layers...first start with darker color but with low opacity and then as u bust opacity lower the color tone...just an idea author...any how this image have potential to be one of the best in the contest...best of luck author
